Objective:To construct a EGFP(Enhanced green fluorescent protein)-labled euk-aryotic expression plasmid of Fcy::Fur suicide gene and to detect its expression in SKOV3 cell line. Methods:With the technology of gene re-arrangement,Fcy::Fur gene in pORF-Fcy:Fur plasmid was subcloned into pEGFP-N1 vector,with its correctness evaluated by the means of r-estriction enzyme analysis and sequencing.It was transfected into SKOV3 cells with lipofectin,the transient expression of GFP was observed under flu- orescence microscope after 24 hours and detected by Western blot. Results:Correct construction of pEGFP-N1-Fcy::Fur was identi- fied by methods of restriction enzyme analysis and nucleotide sequence determination.A total of 60% transfe-cted cells emitted out green fluorescence under fluorescent microscope after 24 h after transfecti-.on. Fcy::Fur gene expressed by the transfected cells were testified by Western blot. Conclusion:The recombinant eukaryotic expression vectors have been constructed successfully and effec- tive-ly expressed in ovarian cancer cells,which may provide an experimental basis for gene therapy of ovarian cancer.

Purpose:Evaluate the prognostic factors in invasive vulvar cancer.Methods:Fifty one cases with invasive vulvar cancer admitted in our hospital from 1980 to 1999 were retrospectively analyzed.Results:Thirty six patients had squamous cell carcinoma and 27 of them were well differentiated and 6 moderately differentiated and 3 poorly differentiated ,three had adenocarcinoma, three had basal cell carcinoma ,three had leimyosarcoma , six had malignant melanoma. Thirteen cases (25.4%) were in FIGO stage Ⅰ;29 (56.7%) in stage Ⅱ;7(13.1%) in stage Ⅲ and 2(3.9%) in stage Ⅳ. The 5-year survival rates of stage Ⅰ,Ⅱ,ⅢandⅣwere 81.5% , 68.4% , 41.2% and 0.0% (P

Many studies indicate that macrophage migration inhibition factor(MIF)is over-expressed in tumor cells,and is involved in the carcinogenesis and tumor development by multiple methods and ways.The complicated molecular mechanisms are not quite clear,and the studies about MIF in digestive tumors,especially in hepatic cell carcinoma become more and more.

Objective To study the effect of rosiglitazone (RSG), the agonist of peroxisome proliferator activated receptor γ (PPARγ), on the proliferation and differentiation of rat osteoblasts and the related mechanisms. Methods The identification of rat primary osteoblasts was performed by alkaline phosphatase (ALP) staining and mineralized nodules. The 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay and p-nitrophenyl phosphate (PNPP) assay were used to observe the effects of different concentrations of RSG on proliferation and differentiation of the osteoblasts. The reverse transcription polymerase chain reaction (RT-PCR) were used to detect the expression of connective tissue growth factor (CTGF) mRNA. The effects of the different concentrations (0,1,2,5,10 and 20 μmol/L) of RSG on TGF-β1-induced CTGF mRNA expression in osteoblasts were detected. Results (1)Different concentrations of RSG could not change the proliferation of osteoblasts (P＞0. 05). (2)Compared with control group, all different concentrations of RSG could suppress ALP activity in osteoblasts (P＜0. 01 ). (3) RSG suppressed the osteoblats CTGF mRNA expression induced by TGF-β1 in a dose-dependent manner (P＜0. 01). Conclusions In vitro, RSG can inhibit the TGF-β1 induced rat osteoblasts CTGF mRNA expression. RSG may play a potential role in preventing the differentiation of the rat osteoblasts.

[Objective] To observe the clinical effect of Jiedu Qinghuo Drink on children infection mononucleosis(IM). [Method] Randomly divide 54 cases into treatment group 27 cases and control one 27 cases. The control one was given Ganciclovir, the treatment one added with Jiedu Qinghuo Drink. [Result] The total effective rate was 85.19% for treatment group, and 55.56% for control one, the comparison of both had difference. [Conclusion] Jiedu Qinghuo Drink has good cure effect on children IM.

Intralipid is a kind of important fat emulsion.It has been widely used clinically in severely ill patients,especially in the patients before and or after major operation since the 1980s.After retrieving the papers on Intralipid form MEDLINE CD ROM database from 1980 to 1994 and analysing them by linear regression analysis in literature metrology,We found a significant linear correlation between the yearly literature quantity and the dynamic time course (year).From 1980 to 1994,the average yearly growth rate of the literature was 1.16.According to the regression equation,it is predicted that the literature on Intralipid will increase at a rate of 2.07% per year.From this analysis,we think that the research of Intralipid is tending to stability and will be wonderful.

Objective To investigate the clinical effect of cefoperazone sodium and sulbactam sodium. Methods 56 cases who used cefoperazone sodium and sulbactam sodium for anti -infection were selected as the observation group,and 56 hospitalized patients who used cephalosporin ceftazidime were selected as the control group. The observation group was intravenously injectioned cefoperazone sodium and sulbactam sodium,the control group received intravenous ceftazidime.The clinical efficacy and adverse reactions of the two groups were compared.Results After treatment,the cure rate and total effective rate of the observation group were 55.36%,98.21%,which of the control group were 35.71%,91.07%.The cure rate of the observation group was significantly higher than that of the control group (χ2 =4.356,P <0.05),and the total effective rate between the two groups had no statistically signifi-cant difference (χ2 =2.817,P >0.05).The incidence rate of adverse reactions of the two groups had no significant difference.Conclusion Cefoperazone sodium and sulbactam sodium therapy has good clinical efficacy in the treat-ment of infectious diseases,and has low incidence of adverse reactions,good safety,which can be popularized and applied in clinic.

Objective To explore the best fat liquefaction prevention measures for gynecological obese patients with abdominal incision.Methods 84 gynecological obese patients with abdominal incision were divided into the observation group(46 cases)and control group(38 cases),according to the negative pressure attract ball placed or not in the subcutaneous fat layer during operation.Patients in both groups were taken abdominal incision physiotherapy.Results The fat liquefaction rate of the observation group was 8.7％,which was lower than that of the control group(26.3％)(x2=4.65,P＜0.05).Conclusion It is very important to keep the incision dry,smooth drainage for prevention and treatment of fat liquefaction in gynecological obese patients after abdominal incision.

Immune factor is one of the main mechanism of children glomerular diseases. Tacrolimus has a strong and effective immunosuppressive action comparing with CsA. In recent years,the curative effect of ta-crolimus in the treatment of children with kidney disease has attracted doctors attention. Tacrolimus in the treat-ment for refractory nephrotic syndrome ( steroid-dependent nephrotic syndrome, steroid-resistent nephrotic syn-drome and the frequent recurrence of glomerular syndrome) has obtained the good effect. This article reviews the application of tacrolimus in nephrotic syndrome,focal segmental glomerular sclerosis,mesangial proliferative glo-merulonephritis,membranous nephropathy,lupus nephritis( LN) in the children with kidney disease.
